Mechanic: It will act like an fusion of A-34 and Z-34, but, its aim-script will get slightly bigger every 5-8 rooms, while making your screen shake even more when it gets even nearer to the current room, shooting an melting orb every 2.5-5 seconds. Also, the puddles or acid can also damage you if you are hiding in a table. It Will Despawn after 20-22.5 seconds.
